Overwrite the timezone for JS/pixel/corpus tests on Linux
Set the TZ environment variable in test_runner.py, so all test suites
that use it run tests in the same TZ. Use America/Los_Angeles, AKA
PST/PDT, as that is what the existing test expectations assume.
For now, just do this on Linux, since that is the platform currently
failing the continuous build. Whereas trying to do this on Windows seems
to have the opposite effect and actually triggers the issue.
